SKIRT MARKER.

Application filed August 1*?, 1921. 'SeraLNd 492,955. K

It is an object of theinvention to pro-r vide a practical skirt marker of simple A,and inexpensive construction, the use of which shall not tire the operator, and which more particularly shall obviate the need for bending down.

In the preferred embodiment, the appa. ratus is ofthe type in whichythe mark is effected by the yejection of powdered chalk through a nozzle and in the application of the invention to this type of apparatus, it is another'object to avoid fatiguing of the hand in operation, and particularly to readily eiiect a sharp and distinct line without the need for grasping and repeatedly compressing a pneumatic bulb. the preferred embodiment, the powdered chalk is enclosed in a flexible reservoir such as a pneumatic rubber bulb adjacent or in proximity to the nozzle," the pressure upon the bulb being effected preferably through a plunger of'sufticient length to be conveniently operated by downward manual pressure. l

According to another feature, a simpley casing unit is provided enclosing the powder containing bulb and having formed integrally therewith the nozzle through which the powder for makin@ the mark is ejected, a conduit connecting til-ie mouth of the bulb to the nozzle.

In the accompanying drawings in which Fig, 3 yis a transverse sectional view taken along the line 3-3 of Fig. 2, y Fig. l is a perspective view of a modified form of the invention,

Fig. 5 is av view in longitudinal section taken along the line 5 5 of Fig. 6, and ;k

Fig. 6k is a top view of one of the preferred forms of marking units. y

Referring now to the drawings, and particularly to Figs. 1, 2 and 3, l have shown a skirt marker comprising a base 1 preferr-r ably hollow1 and weighted with yplaster of l Paris as at 2 and including anintegral fer-k rule 3 for retainino' the u vstandin frame structure of the device. This structure comprises preferably an ordinary yard stick 4 having secured to a face thereof by any desired means the base 5 of a rectangular bar 6 having a longitudinallyextending groove 23. `fidjustably secured to the frame is the marking unit which in the present embodiment comprises a casing 7 preferably of sheet metal having an extension y8 ,fitted about the frame and slidable therealong and carrying a clamping lever 9 havingV an ec centric conformation l0 by which the marky ing unit can be clamped in desired position upon the frame. The casing 7 has vertical sides 11 each tapering to an apex 12, and a horizontal top 13 integral therewith connects said sides, there being formed `integrally with the top and connected' with the apices of the sides a small nozzle tube 14 extending along the forward edge of the top and having a longitudinal slit 15. The top 13 of the casing has preferably an in tegral downward extension 16 with an integral forwardly extending reaction plate or support` element 17 upon which rests preferably a pneumatic rubbery bulb 18 containing powdered chalk 19.v The mouth of the bulb 18 is connected by a yconduit 21 eX# tending preferably on the exterior of the casing to one end of the tube 14C, the other` end of said tube being closed as at 22. Slidably iitting in the groove 23 of the U-bar there is a plunger rod 24 guided at its upper end by a ferrule `25 on the frame and guided by the ferrule 3 at its lower end. The plunger has an operating knob-26 at its top and carries intermediate its ends ya presser comprising preferably a sheet metal stamping 27 extending at its lower end lain, K

casing and having a rounded end formed preferably by a ferrule 29 enclosing the lower edge' of theblank and" engaging the top ofthe? bulb' lS'ly The presser is preferably adjustably secured to the rod bymeans of a sleeve 30 encirclingithe rod and having a lateral nipple 3l extending through an aperture in the presser blank 27, a nur? 32 threaded upon the nipple serving to clamp the presser in positionl upon'the plunger.v A `setL s crew is threaded through the center*` ofthe nipple' and clamps the 'sleeve surepreferably a gentle slapwith the palm" skirt atA the desired elevation.

against 'the rod'. The bottom or reaction pla-tiel l? upon which the bulb 18' rests is Preferably formed triighfll symmetrical withy respect to the operative'` ei'idi of the presser a'ndfof width' mateiially smaller thanl thedianieterof the bulb.

Preferably `the ferrule 29 at tlie'end of the presser li'as a short extension 35 beyond tliefsldt 28 ,preventing the accidental ren'iov'- al' o'f the pressery from theslot in the process l' ,of` adj ustme'nt.

Near the upper. end preferably a coil'.A

springllencircles the plunger rod andmis secured at' one endto the frame structure as at and at thel other end tothe plunger ashat 38 to. mainta'in 'it'.win. the. upper or rais'ejdiposlition show'n in Fig. 2. The upper edge 39A of, the clamping' end of the markingfunit,Y Wliieh travels directly over' the scale 'onth'e frame, is preferably. in alignmentA with the nozzleV slot 'l5 so that vthe elevatien of" the nozzle Lfrom the floor will:

be indicated by. the position of said edge 89 with respect'to the' scale;

To adjust'tlie marker' in desired'elevation, theset screw l33an`d` the clamp 9 are both loosened; Vthe marking unit 7 is moved up or down until the 'edge 39 is at the scale marking` indicating tlie elevation. desired, the presserl 27r beingIk moved upfor down with the `marker iint'il'the desired' position is reached, Ywher'calpen'the setscrew and theclamp `9. are' tightened. The marker is 15' against .the 'skirt,yand by a. simple pres'- ofithehantlliupvon the knob' 26; a sharp and clear-"'clialk line will bev produced upon the seeii" thatv the depressionV of'A the plunger against spring 3,6 caused byy the manual pr'ess'ili'eiirg'es lthe edge 29`-of the presser 27 aga-nistL the bulb, pressingthe'maj or part A therebt" intov t'hegroove 341, thus forcefully ejectin-g theta-ir'. which blows a' small'quantity-"off"cha-ll outf of the bulb through the conduit 2'1`into'the tube, the chalkemerging-==tlir'oiighlftlienslity l5,- thus forming the desiredV` mark. As'- soon as the hand isf-remo'lfedf from` the knob', the spring 3G' re stores the* plu-nger tofrais'ed position and air 'enters Ithirough slitflL to' againA restore with a longitudinal' It will bev the bulb to expanded state. This operation may be repeated, the person slowly turning andf depressing the knob at' intervals in orderl to produce a continuous' chalk line about the skirt.

In Figs. 4i, 5` and 6 is shown a modified form of the invention which is even simpler than that of Figs. l, 2 and 3. Those elements that are common to the two embodi- .ll tothe lower end of the operating bar l24 and extending at its forward end through a slot 45 in the top 46 of the marker casing and having a forwardly extending toey 47 in surface Contacty with. the bulb.

ln the specific embodiment shown', the

' casing is formed with an integral'rectangular sleeve 4:8 encircling the yard stick Ll0 and a set screw 4:9 extending through the' rear surface 50`1of saidsleeve for clamping the casing in any desiredposition on the' yardstick ln this embodiment, the casing is shown with a flat bottoni 51' and' a bentover forward edgef52fextending upwardly therefrom, it. being understood that the ilat toe il? of the presser willv exert pressure upon the bulb through a' suflicienti area' to effectively compresstlie same,.without` like# lihoodof laterali deflection of the bulb away from the presser. lf desired,`of course, the.v groove 34 shown in Fig'. 2 maybeenfi'ployed.vr

The upper rearedge 53' of the casing, as

in the other embodiment is aligned with the slit 15 of the nozzle, so that the elevation ofthe nozzle in this case will'y also' 'be de- Y f 'termined by the reading of said'edge upon theya-rd stick.

Tn operation, assuming.'

the marker'v unit to have been set iny proper position asin the case previously described, the lowermend` of the yard stick is placed upon the: iioor and the unit held Verticallyivith thenozzle l5 in close proximity to the skirt and the upper bar 42 is simply pressed downwardly, compressingv the bulb 18 to causethe ejection of powder 19 from the nozzle againstl the` skirt( When the pressure of thehand is' released, the bulb rapidly expands ,b'y in'l take of air, raising the presser toe i7 and wit it the light operating b'ar l25to the home position indicated in Figs.- 4 and 5, whereupon the operationimay be repeated.

The construction of Figs. 4,5 and 6 `is iasos particularly simple involving merely two sticks, both of which may be yard sticks, if desired, or one of which may be an ordinary stick without graduations held in slidable relation with respect to each other by a simple strap el, a simple sheet metal presser 43 being secured to the upper of said bars and the inexpensive metal casing enclosing the rubberl bulb being adjustablyy secured to the other, the return of the parts to. their original position after operation being eiected by the bulb Without the need for a return spring. Obviously, the metallic parts of this form of skirt marker, may be sold or distributed apart from the yard sticks to fflressmakers, tailors or housekeepers to be attached to such yard sticks, as required,

lt will be seen that by my invention, the pneumatic bulb is in close proximity to the slit or nozzle from which the powderl emerges, so that ythe rubber conduit is short and the chance for leakage correspondingly small. The plunger is an ordinary rod actu ated by simple pressure with the palm, as indica-ted in the drawings, aliording an etective compression of the bulb and a correspondingly strong blast to form a sharp and distinct line, which will be distinctly visible not only upon dark woolen goods but also upon silks or satins of light shades. lt instead of the use of a plunger for actuating the device, the. hand-pressed pneumatic bulb is used and if such bulb is at a suiiicient elevation to be conveniently grasped by the hand without bending down, it is apparent that a relatively long conduit would connect the bulb to the nozzle so that a materially greater volume oi air would be enclosed than in my construction. As is Obvious from elementary principles of'physics, the compression of the bulb by the hand would consequently increase the pressure of the confined air less than in my construction, so that the 'force with which the powder would be ejected through the slit would be lower and the line rwiould not ordinarily have the required sharpness and distinctness :to-r practical purposes, particularly it applied to light-colored silk skirts. It is, moreover, to be observed that the process of reaching 'for a bulb, grasping it and pressing it hard repeatedly in making the line will tire the muscles oi1 the hand and forearm. while, by my invention, the simple application of downward pressure with the palm constin tutes no eiiort, but on the contrary, actually tends to rest the hand.

il. single filling of chalk is sufficient to mark many dozens of skirts. `When the supply of chalk is exhausted, the plunger is depressed, the nozzle slit l5 placed under the surface oi" powdered chalk in a box and upon allowing the plunger to rise, it is apparent that chalk will be sucked into the bulb to substantially fill the same, in a manner similar yto the filling of a dropper or syringe.

lt will thus be seen that there is herein described apparatus in which thev several features vorf this invention are embodied, and which apparatus in its action attains the various objects of the invention and is well suited to meet the requirements oi1 practical use.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above descrip tion or shown `in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.. i
